Type species: amplificata Walker.
The facies in this genus is very similar to that of Polynesia, except
the red postmedial is entire, grey-centred, and the hindwing lacks strong angles
or 'tails' at the margin, though the red spots are similarly more intense in
these positions. The male antennae are filiform.
The genitalia of both sexes are distinct from those of Polynesia. The
male has a U-shaped sclerite distal to the eighth sternite, and the saccus is
modified in a complex manner to support large corematous structures. The uncus
is vestigial, the tegumen broad, oval. A broad complex structure between the
valve transtillae may be derived from the labides. The valves are rectangular,
constricted basally, with setation similar to that in the Eupitheciini genera
The female has a short, strongly sclerotised ductus that is constricted
where it joins the corpus bursae. The latter consists of a globular, extensively
spined basal portion and a small more flimsy distal portion, the two separated
by a narrow, tubular portion.
The genus consists of an allopatric array of at least two species that extends from Sundaland to New Guinea.
